Answer:
0.3, 33%, 1/3, pi x 10-1
Step-by-step explanation:
Let's simplify all of them so that they're in the same form. 33% is 0.33 as a decimal, since a percentage is out of 100. 1/3 is equal to 0.33333 repeating as a decimal--This one is just one that you have to memorize. 1 divided by 3 will give you your answer. Next, pi multiplied by 10: pi is roughly 3.14159 to the hundred-thousandths place. So we multiply that by 10, giving us 31.4159. -1 gives us 30.4159.
So:
0.3, 33%, 1/3, and lastly pi x 10-1
Answer:
There were 84 students in 6th grade, 68 in 7th grade, and 90 in 8th grade.
Step-by-step explanation:
Given that Elk middle school has 264 students, and there are 84 students in the eighth grade, and there are 22 fewer seventh-grade students than sixth-grade students, to determine how many students there are in each grade, the following calculation must be performed:
(264 - 84) / 2) - 22 = X
(180/2) - 22 = X
90 - 22 = X
68 = X
6th grade = 84
7th grade = 68
8th grade = 90
Therefore, there were 84 students in 6th grade, 68 in 7th grade, and 90 in 8th grade.

Answer:
r = -4/5
Step-by-step explanation:
Divide both sides by 15 so you have r
-12/15 simplify (both by 3)
-4/5
Answer:
x = 1/2 and x = 9/2
Step-by-step explanation:
To solve this equation: |2x-5|=4 we need two evaluate two cases:
|2x-5| = 2x-5 when x>5/2 ✅
|2x-5| = -2x+5 when x<5/2✅
Then, if x>5/2:
2x-5 = 4 ➡ x = 9/2
Then, if x>5/2:
-2x+5 = 4 ➡ x = 1/2
Then, the two solutions are: x = 1/2 and x = 9/2
